HINGE.

SPECIFICATION forming part of Letters Patent No. 615,690, dated December 13, 1898. Application filed July 2, 1897. Serial No. 643,251. (No model.)

To all whom it may concern:

Be it known that I, ALEXANDER G. EsoH WEILER, a citizen of the United States, and a resident of Milwaukee, in the county of Mil- ,forth with reference to the accompanying drawings, and subsequently claimed.

Figure l of the drawings represents a sectional view of a window-frame and an inside swing-sash connected thereto by means of hinges in accordance with my invention, the sash being in position to close the window; Fig. 2, a horizontal section of a portion of the window frame and sash; Fig. 8, a perspective View of one of the hinges, having its sash-leaf elevated and swung outof normal position; Fig. 4, a similar view of said hinge, having its sash-leaf in normal position; Fig. 5, a horizontal section of the hinge, having its sashleaf elevated and swung out of normal position; and Fig. 6, a like view of the hinge, having its sash-leaf in normal position.

Referring by letter to the drawings,,A represents the head of a,window-frame, and B the top rail of an inside sash in swing-hinge connection with a jamb C of said frame, this jamb being provided with a groove with which a stile D of said sash has engagement when the latter is in position to close the window, as shown in Figs. 1 and 2. When the sash is in its normal position, as herein shown, its top rail B comes snug against the head A of the window-frame and the inside of its foot rail is lapped by an ordinary stool F on the sill G of the said frame. Before the sash can be swung to open the window it must have direct vertical lift to clear the sill stool. There fore the frame and sash connecting hinges must have their sash-leaves movable in a vertical direction, and clearance for lift of said sash must be had between the top rail of same and the window-frame head, it being prefer-' able to have said sash-rail and frame-head in loose rabbet-joint engagement, as shown in Fig. 1.

Each of the hinges herein shown has its pintle H in rigid connection with a stud pro? jection bat thelower inner corner of the j ambleaf I thereof, and surmounting this stud projection is a horizontal flange 0, having a rightangle notch flanking the inner side of said leaf. The projecting knuckle d of the sashleaf J has vertical as well as pivotal play on the pintle H and rests on the jarnb-leaf flange when in normal position. However, it would be practical to have the pintle I-I rigid with that portion cl of sash-leaf J and loose in that portion 1) of jamb-leaf I to thus provide for the necessary vertical and pivotal movement of said sash-leaf, this being a mere reversal of what'has'been previously described; but in either case the upper and lower knobs herein shown are mere ornaments, neither of them being necessarily a part of said pintle,

the foot-lug and have less than the full width of the sash-leaf extend below its stud.

In practice the jamb-leaves of the hinges are concealed by the window-casing K, and the other leaves of said hinges are set in the stile D of the sash to stand at right angles to the former leaves when said sash is in normal position with relation to the window-frame.

'To open the sash, the same is first lifted until its foot-rail E clears the sill-stool F of the window-frame, the sash-leaves of the hinges being then clear of the notches in the flanges c of the jamb-leaves. This clearance being had the sash is swung inward and supported in more or less open position, the sash-leaves of the hinges having the lower horizontal edges thereof at rest on the flanges c of the jamb-leaves.

When the sash is swung back, it has vertical drop as soon as the sash-leaves of its hinges come into register with the notches in the flanges of the janlb-leaves, and the bottom rail of said sash coming outside of and against the sill-stool F the window will be Weathertight when closed.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

A hinge comprising a jamb-leaf having a lower inner corner projection surmounted by a horizontal flange provided with a right-angle notch flanking, the inner side of said leaf, and a sash-leaf in pintle connection with the jamb-leaf to have vertical as well as pivotal p1ay,a portion of the sash-leaf beingextcnded ALEXANDER O. ESCIUVEILER.
